With engine runaway, you could always use the decompression lever to open all the exhaust valves. That ought to bring it back under control. In reality though, do you want to get anywhere near an engine that is going to self destruct in the very near future? Engines are cheap (relatively), and the safest policy is probably to run away as quickly as you can. > I'm not sure but I suspect the FR injector pump is external to the > crankcase.

It's just occurred to me to wonder if I've got a leak across the cylinder head gasket between a cylinder and an oil way. That would certainly cause the oil mist I'm seeing. Although, it would affect the silky smooth running of the green machine, so it probably isn't that. Anyway, I could put my thumb over the hole and keep it there while I would expect a leaky cylinder to rapidly pressurize the crankcase beyond what I could restrain. Also, a leaky cylinder would cause the dreaded diesel up the exhaust problem and I'm not seeing any indications of that problem again. > In former times.
